Reading the passage
Emeagwali thinks nature offers useful ideas for computing, and he expects other scientists to look there increasingly. We need a view his work or statements support. Our own skepticism about one of his claims doesn't become his opinion.
Working the answers
- ACorrect
Trees have efficient branching structures; he adapts their underlying principle to improve a computing network. That is an example of a natural solution being useful for an analogous technical problem. The honeycomb design supplies another example of his approach.
- B
This is the opposite of his stated optimism. He claims his weather design will be powerful enough to predict patterns “a century in advance.” We may question that claim, but he doesn't express B's limitation.
- C
“Increasingly” doesn't mean more than half of all designs. Nature-inspired designs could become more common while remaining a minority.
- D
Nothing predicts their use for routine jobs. A system suited to complex oil-flow calculations needn't become the practical choice for ordinary computing.
- E
Oil-flow prediction is one use of the tree-based design. The text doesn't rank it as the structure's primary use. The fact that the principle helps distribute calculations doesn't remove its oil-field application; the unsupported claim is that this application comes first.
